If you have a VPN App or profiles installed, or a security/AV/firewall App such as Norton, these may be interfering with your iPad's network stack - even if the VPN connection is seemingly turned off. If applicable, the resolution is usually simple; if installed, you may need to remove the Security App and/or VPN from the device.
If this resolves your issue, the VPN and/or security App can be reinstated after the connectivity problem has been resolved.
If some Apps are working as expected, while others are not - or other devices can connect to your WiFi network - you may find that a restart of your WiFi Router, followed by a restart of your iPad will clear the problem….
To restart your router, disconnect power from the router for at least 30 seconds - then reconnect power to restart. After your router reboots (which may take several minutes), force restart your iPad:
Force restart iPad (models with Face ID or with Touch ID in the top button)
If your iPad doesn’t have the Home button, do the following:
- Press and quickly release the volume button nearest to the top button.
- Press and quickly release the volume button farthest from the top button.
- Press and hold the top button.
- When the Apple logo appears, release the top button.
